PATENT IAMES MARSHALL,4 OF 'FALL RIVER, MASSACHUSETTS.

MEANS FOR coNvEYlNe'sTI-:AM FROM Tues.

SPECIFICATION forming part of Letters Patent No. 573,340, dated December 15, 1896.

` Application filed January 31, 1896. Serial No. 577,559. (No model.)

To @ZZ Loh/0712, 'zit may con/cern:

Be it known that I, JAMES MARSHALL, a

citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Means for Con` troubled with said escaped steam, which is of such enormous quantities as to completely iill the room, thus making it damp and unhealthy, besides being very inconvenient, in that it is impossible to sce but a short distance.

It is the object of my invention, therefore, to provide means for relieving the above trouble which shall be thoroughly practical, compact, reliable, and whereby one or a series of tubs may be connected with a single vent and drain pipe, which is provided with means for creating a circulation of air, thereby form-` ing a suction to draw out the steam in the tubs;

Upon the accompanying drawings, forming part of this specification, similar referencecharacters denote like or corresponding parts upon the several figures, and of which- Figure l shows a plan view of a double series of tubs provided with my improvements. Fig. 2 is a cross-section on line c a: of Fig. l and showing two double series of tubs instead of one. Fig. 3 is a central vertical section on line @j y of Fig. l.

From the above figures it will be apparent that I preferably arrange my sizing-tubs in double rows in a straight line upon the bottom iioor of the building andpartition the saine off in pairs and connect them Separately with the drain-pi pe. Each row of tubs is provided with a continuous sizing-board which extends along their entire length. Thus the attendants employed face each other while at their work. Y

` the hat-bodies in sizing the same.

Referring to the reference-characters upon the drawings, l indicates the floor of the building, which may be formed of cement, concrete, or any suitable material, and of such grades as may give the best results for proper drainage. t

2 indicates posts to support the ceiling of theroom, and 3 platforms upon which the operators stand while engaged in sizing the long series of tubs, A and B, the outer walls of which are preferably vertical and flush with the framework, while the inner walls are inclinedly constructed. These tubs are separated by intermediate walls 5 and are further provided with partitions (i, whereby a single tub of each series is connected with that of the opposite tub and whereby they are separately connected with the drain and used simultaneously. Immediately above the space between the two series of tubs and their partitions I provide a covering 7, which serves as a shield or deflector and covers about half of the Vinner `top portion of said tubs, thus making only the outer portion thereof apccessible to the operator and whereby the only air-inlet to the space between the tubs and the outlet-vent is through the opening which I indicate as S, and which appears between the outer end of said covering 7 and the waterline of said tubs.

To the out-er wall of the rows of tubs I attach `an inclined operating-table 9, which is preferably formed continuous throughout the length of the series of tubs, and serves as means upon which the operators manipulate The tubs are each provided with a hot and cold Water supply-pipe l0 and ll, respectively, each of which are fed from a larger pipe running lengthwise with said tubs, andwhich serve as a supply for the pipes 10 and l1 before mentioned. I also provide'a third pipe l2, which is for the purpose of conducting steam from the main pipe 13 to the several tubs in substantially the same manner that the water is supplied thereto, and for the purpose of heating the same. It will further be observed that these several water and steam pipes are IOO provided with suitable valves 14, by ineans of which the several supplies are governed.

Beneath the iloor of the building and in line With the tubs I form a large sewer or vent C, one end of which extends through the outer foundation-Wall of the building and empties into any suitable drain. Adjacent to the said terminus of this vent I place a blast-fan D, by means of which I create a violent circulation Within the vent-pipe C, thus causing a suction through the spaces 8 and the several vert-ical pipes l which connect said vent-pipe with the several pairs of tubs and serve to cause the steam and odors fro-1n the Water and hat-bodies of said tubs to be drawn into the vent and finally discharged from the building. I also connect with the vent-pipe C suitable drainpipes 1G, which are provided With traps 177-, the perforated mouth of Which finishes flush with the top of the valleys of the floor l, thereby relieving the same of all surplus Water, thu-s serving to keep the same clean and dry at all times.

It is possible with theconstruction such as I have shown and described to relieve a hatfa-ctory of all steam, smoke, and odors which have previously existed in my factory and which noW exist in the majority of factories in the country, and which are 'decidedly objec-ti-onable for many reasons.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-` 1. In a device of the class described, the combination with a double series of sizingtubs, of a series of housings, partially covering pairs of said tubs, a main vent-pipe, arranged adjacent to said tubs, independent connections between said pairs of tubs and the main vent-pipe, means Within said ventpipe whereby said steam and odors are carried off, substantially as described.

2. In a device of the class described, the combination with a series of sizing-tubs, of a main vent arranged adjacent to said tubs, partitions whereby said tubs are partially inclosed, connections between said inclosure and the vent-pipe, and means for carrying oir" the odors through said pipe, substantially as described.

3. In a device of the class described, the combination with a double series of tubs, of a series of partitions between and dividing the saine into pairs, an air-inlet opening above said tubs, connections therefrom with a main ventpipe having an air-blast therein, means whereby the several pairs of tubs may be vdisconnected from the main vent-pipe, substantially as described'.
